800米 视频电源共缆传输
<br />
SPVD( Share Power video device)是一款专利技术的一线混合传输视频和电源的共享设备，彻底改变了安防行业里传统的视频、电源线缆分别布线传输的方式，专门解决了安防系统中摄像机前端独立供电、实时传输图像距离近的难题；具有抗干扰能力强,传输距离远，安装便捷的特点。本产品通过一根线缆传输图像的同时，也给摄像机供电,为用户节约了大量的线材、人力、物力,可以广泛应于系统改造和新系统建设工程.是一款新型绿色环保节能的专利产品。<br />
本产品采用国际领先的数字变频专利芯片和共缆传输自适应技术；以双芯电缆(视频线、双绞线、电缆)为传输介质,将电源和视频信号叠加进行数字变频处理并进行还原补偿处理，提高信号增益及抗干扰能力,从而有效的避开各种电磁及射频干扰,使传输的图像更稳定、更清晰,施工维护也更方便、更快捷。
